Imbali: Ngaba ngumhlobo okanye ulutshaba? ... okanye uFrenemy?

Imbali: ngaba yeyona khemikhali icaphukisayo emzimbeni?

[Imbali yemolekyuli] “IBleh”

Zizinto ezenziwa zii-allergies. Yewena mkhuhlane? Ukutya kokutya? Ulusu lokwaliwa? Imbali idlala indima enkulu kuzo zonke.

Kwaye ezo meko zidlala indima enkulu kuthi. Ngo-2015, idatha ye-CDC ibonise ukuba ngaphezu kwe-8% yabantu abadala base-US babenomkhuhlane we-hay fever. Ngaphezulu kwe-5% yabantwana base-US babenokutya komzimba. Kwaye ubuncinci i-12% yabo bonke abantwana base-US babenokwaliwa sisikhumba!

Ke yintoni isivumelwano? Kutheni le nto sinemichiza ekhathazayo emzimbeni wethu?

Ewe, i-histamine ihlala ingumhlobo wethu.

Imbali yimolekyuli ebonisa, ithumela imiyalezo phakathi kweeseli. Ixelela iiseli zesisu ukuba zenze i-asidi esiswini. Kwaye iyanceda ingqondo yethu ukuba ihlale iphaphile. Usenokuba uzibonile ezi ziphumo ziboniswa ngamayeza athintela i-histamine. Ezinye ii-antihistamines zinokusenza silale kwaye ezinye ii-antihistamines zisetyenziselwa ukunyanga i-acid reflux.

Imbali iyasebenza nakwinkqubo yomzimba yokuzikhusela.

Inceda ukusikhusela kubahlaseli bangaphandle. Xa amajoni omzimba efumanisa umhlaseli, iiseli zomzimba ezibizwa ngokuba zii-B-cell zenza i-IgE antibodies. Ii-IgE zifana ne "ZIFUNWA" iimpawu ezisasazeka kuwo wonke umzimba, zixelela ezinye iiseli zomzimba malunga nabahlaseli abathile ukuba bajonge.

Ekugqibeleni iiseli zemasti kunye ne-basophil ziyayithatha i-IgE's kwaye zenziwe zivuseleleke. Xa bedibana nomhlaseli ojolise kuye ... Bakhupha i-histamine kunye nezinye iikhemikhali ezivuthayo.

Imithambo yegazi iyavuza, ukuze iiseli ezimhlophe zegazi kunye nezinye izinto ezikhuselayo zinokungena zize zilwe nomhlaseli.

Izenzo ze-Histamine zilungile ekukhuseleni umzimba kwizidleleli.

Kodwa ngenxa yokugula komzimba, amajoni omzimba asabela kwizinto ezingenabungozi, hayi iiparasites. Kulapho i-histamine iba lutshaba lwethu. Izifo eziqhelekileyo zibandakanya amandongomane, impova, kunye nesilwanyana.

Iinqanawa ezivuzayo zibangela ukukrazuka emehlweni, ukuxinana empumlweni, kunye nokudumba ... naphi na. Imbali isebenza ngemithambo-luvo ukuvelisa ukurhawuzelela. Kwizidlo ezaliwa komzimba kunokubangela ukugabha kunye norhudo. Kwaye inyanzela izihlunu emiphungeni, yenze kube nzima ukuphefumla.

Eyona nto ibaxekileyo kuxa i-histamine ibangela i-anaphylaxis, impendulo ebukhali enokubulala. Ukudumba komoya kungathintela ukuphefumla, kwaye ukwehla okukhawulezileyo koxinzelelo lwegazi kunokubulala indlala kwizitho zegazi elibalulekileyo.

Ke yintoni enokwenziwa nge-histamine?

I-Antihistamines ibhloka iiseli ekuboneni i-histamine kwaye inokunyanga ukwaliwa komzimba okuqhelekileyo. Amayeza anje ngee-steroids anokuthomalalisa ukudumba komzimba. Kwaye i-anaphylaxis kufuneka inyangwe nge-epinephrine, evula iindlela zomoya, kwaye inyuse uxinzelelo lwegazi.

Ke ubudlelwane bethu ne-histamine bu… bunzima. Sinokwenza ngcono.

I-NIH kwaye ngokukodwa iZiko leLizwe lokuLwa nokuNwa kwezifo eziSulelayo (i-NIAID) lixhasa uphando lwe-histamine kunye neemeko ezinxulumene noko. Inkqubela phambili enkulu iyenziwa ekuqondeni izinto ezibangela ukungabikho komzimba kunye nokulawula iimpawu zokungabikho komzimba, kunye nokuqonda ukuba kutheni i-histamine, i-frenemy yethu, isebenza ngendlela eyenzayo.

Fumana uphando oluthile oluhlaziyiweyo kunye namabali avela kwi-medlineplus.gov kunye ne-NIH MedlinePlus kwimagazini, medlineplus.gov/magazine/, kwaye ufunde ngakumbi ngophando lwe-NIAID ku- niaid.nih.gov.
